Background: Plant-based proteins as an alternative to synthetic polymers have attracted the interest of the global packaging industry in the last decade due to their biodegradability, sustainability, environmental, and beneficial health claims. Scope and approach: This review covers the recent developments in biodegradable packaging such as edible films/coatings and innovative packaging materials based on plant protein sources. The importance, sources, and techno-functional properties of plant-derived proteins for food packaging are discussed. The impact of different additives on the functionality of plant protein-based biodegradable materials is also investigated. In addition, plant protein-based packaging characteristics and their application in food are also introduced. Key findings and conclusions: The sustainability, biodegradability, renewability, and appropriate mechanical and techno-functional properties of proteins from plant origin make them an emerging substitute to the conventional synthetic polymers currently used as food packaging. The functional performance of plant protein-based biodegradable materials can be extended or enhanced by incorporating other additives or biopolymers. Bio-packaging materials made from plant-based proteins provide great potential for enhancing food quality and safety, reducing the environmental pollution.

Plant protein-based nanocomposite films: A review on the used nanomaterials, characteristics, and food packaging applications
Jafarzadeh, Shima; FOROUGH, MEHRDAD; Amjadi, Sajed; Javan Kouzegaran, Vahid; Almasi, Hadi; Garavand, Farhad; Zargar, Masoumeh (2022-01-01)
Consumer demands to utilize environmentally friendly packaging have led researchers to develop packaging materials from naturally derived resources. In recent years, plant protein-based films as a replacement for synthetic plastics have attracted the attention of the global food packaging industry due to their biodegradability and unique properties. Biopolymer-based films need a filler to show improved packaging properties. One of the latest strategies introduced to food packaging technology is the producti...
Cinnamon oil Nanoemulsions Microemulsions Formulation Characterization and Antibacterial Activity
Yildirim, Simge Tutku; Soyer, Yeşim; Öztop, Halil Mecit (null; 2015-08-10)
Health and environmental concerns due to usage of synthetic active materials in foods and packaging technologies have increased the demands of using natural additives and the researchers conducted in this area. The purpose of this study is to obtain stable nanoemulsions (NEs)/micro emulsions (MEs) which are formed by using cinnamon oil that has high antimicrobial activity for enhancing the quality, safety and shelf life of foods. In the literature, it was found that cinnamon oil had high antimicrobial effec...
Treatment of silk production wastewaters by membrane processes for sericin recovery
Capar, Goksen; Aygun, S. Seylan; Gecit, M. Rusen (Elsevier BV, 2008-12-01)
Sericin protein, although a valuable resource for many industries including cosmetics, pharmaceutical and biomedical, has been discarded as a waste in silk industry, causing environmental pollution. This paper describes determination of a membrane-based process for sericin recovery from cocoon cooking wastewaters (CCW) that will enable value-added utilization of waste sericin. The iso-electric point (pI) of sericin was found as 5-6, whose MW was distributed as 180-200, 70-80, 30-40 and 10-25 kDa. Prior to m...
Preparation of antimicrobial films from agricultural biomass
Seber, Ayşe Gizem; Bakır, Ufuk; Department of Biotechnology (2010)
Mainly used food packaging materials are petro-chemical based polymers which present environmental problems since they are not biodegradable and ecologically sustainable. In this study, biodegradable biofilms are produced from xylan, extracted from cotton stalk which is an agricultural biowaste without nutritional value. Antimicrobial property was given to the biofilms with either titanium dioxide sol-gel coatings or titanium dioxide powder addition into the biofilm forming solutions. The antimicrobial acti...
The control of fungi and mycotoxins by food active packaging: a review
Jafarzadeh, Shima; Hadidi, Milad; FOROUGH, MEHRDAD; Nafchi, Abdorreza Mohammadi; Khaneghah, Amin Mousavi (2022-01-01)
Conventionally used petrochemical-based plastics are poorly degradable and cause severe environmental pollution. Alternatively, biopolymers (e.g., polysaccharides, proteins, lipids, and their blends) are biodegradable and environment-friendly, and thus their use in packaging technologies has been on the rise. Spoilage of food by mycotoxigenic fungi poses a severe threat to human and animal health. Hence, because of the adverse effects of synthetic preservatives, active packaging as an effective technique fo...
